Natural Radioactivity

Science > Physics > Nuclear Physics > Natural Radioactivity Radioactivity was discovered by French physicist Antoine Becquerel in 1896. He found that certain compounds of uranium emitted invisible radiations which affected photographic plates. It is also found that Thorium and its compounds also show these properties. Madame Curie and Piere Curie discovered two elements namely […]

Introduction to Reflection of Light

Science > Physics > Optics > Reflection of Light > Introduction to Reflection of Light When a ray of light approaches a smooth polished surface and the light ray bounces back, it is called the reflection of light. The surface which reflects the light is called a reflecting surface. The ray of light approaching the […]

Octet Theory

blank

Science > Chemistry > Physical Chemistry > Nature of Chemical Bond > Octet Theory The force of attraction which keeps atoms or ions together in a molecule is called a Chemical bond. The main cause of chemical combination is the tendency to acquire stability i.e. a state with minimum energy and a tendency to acquire […]
